Contract Usage Ranker

Groups a wallet’s transactions by destination and ranks them by gas spent rather than by call count, because the contract you touched most is rarely the one that cost you most — and when those two answers differ, the app says so explicitly rather than letting you draw the wrong conclusion. Costs use effectiveGasPrice, which is what was actually charged; a transaction’s own gasPrice is only the cap and overstates spend wherever a base fee applies. Function selectors are named where recognised, reverted calls are counted per contract, and a second ranking groups by action so you can see whether approvals or swaps are where the money went.
